+Power management
+----------------
+
+For power management (particularly DVFS and AVS), the North Bridge
+Power Management component is needed:
+
+Required properties:
+- compatible : should contain "marvell,armada-3700-nb-pm", "syscon";
+- reg : the register start and length for the North Bridge
+ Power Management
+
+Example:
+
+nb_pm: syscon@14000 {
+ compatible = "marvell,armada-3700-nb-pm", "syscon";
+ reg = <0x14000 0x60>;
+}
